# Description: This file is used to be assign network configuration based on a data file. It is intended to put as a start up service or put it in the rc.local file.
# The data file contains the list:
# MAC address, IP address, netmask, gateway, DNS, ethetnet port, hostname name.
# e.g.
# 00:AA:BB:CC:DD:E1 192.168.1.1 255.255.255.0 168.95.100.254 168.95.1.1 eth0 mars1.domain
# 00:AA:BB:CC:DD:E2 192.168.1.10 255.255.255.0 168.95.100.254 168.95.1.1 eth0 mars2.domain
